When your parents are one of heavy metal's longest-running married couples, you learn a thing or two about commitment -- through both the good times and bad -- and Kelly Osbourne is ready to follow in Sharon and Ozzy's footsteps of locking down true love. The goth girl-turned-fashionista has announced that she and boyfriend Matthew Mosshart, a vegan chef, are engaged, and tells Hello! magazine that the recent proposal during a tropical getaway involved an homage to her dear ol' dad.

Kelly says she remembers being fascinated with one of her father's earrings when she was a kid, and that her similarly designed engagement ring means that memory will always be with her. "I used to hold my finger up to his ear when I was little and say: 'I want a ring like that.' Now I have one!" Kelly and Matthew have been together for two years, and though fans of "The Osbournes" might remember her as guarded, she says meeting Matthew has opened her up.

"Matthew has broken down every one of my walls," she says. "There's nothing I wouldn't do in front of him."
